High voltage (HV) electrical systems that pair solid state relays (SSRs) with electromechanical contactors in order to optimize current disconnections, methods for making/using such systems, and vehicles equipped with such systems are presented. The HV electrical system includes a first circuit loop that connects a rechargeable energy storage system (RESS) to an electrified powertrain. A second circuit loop in parallel with the first circuit loop connects the RESS to a charging inlet of the battery charging system. A first contactor switch on the first circuit loop is connected in series with an electric motor of the powertrain and a first terminal of the RESS battery assembly. A second contactor switch on the second circuit loop is connected in series with the charging inlet and the first terminal. The one or more SSR switches are electrically connected in series with the second terminal of the battery assembly, the electric motor, and/or the charging inlet, and are electrically connected in series with the two contactor switches across the battery assembly.

    呈现了将固态继电器(SSR)与机电接触器配对以便优化电流断连的高压(HV)电气系统、用于制造/使用这样的系统的方法、以及配备有这样的系统的车辆。HV电气系统包括第一电路回路,其将可再充电储能系统(RESS)连接到电气化动力总成。与第一电路回路并联的第二电路回路将RESS连接到电池充电系统的充电入口。第一电路回路上的第一接触器开关与动力总成的电动马达和RESS电池组件的第一端子串联连接。第二电路回路上的第二接触器开关与充电入口和第一端子串联连接。一个或多个SSR开关与电池组件的第二端子、电动马达和/或充电入口串联电连接、并且跨越电池组件与两个接触器开关串联电连接。
